This adapter fits a 14" x 14" opening. Please check your fan requirements. If it is 400mm x 400mm you need to purchase an adapter from our Euro Adapter listing.
Patent Pending adapter matches the contour of the OEM roof so a standard RV style vent mounts to a flat surface. Prevents distorting the roof sheet metal or vent flange and can be used as an aid for locating the fan. They are CNC machined out of UV and fire resistant expanded PVC. The fan mounts to the outside adapter. Fan adapters work with the Maxxfan Deluxe series and the Fan-tastic Vent fans.
Don't be fooled by the lower priced copy cat adapters here on Ebay. We have seen some of them and they are junk! They are not made out of the high quality material that we use.
It is important to use our Interior support framing system. https://www.ebay.com/itm/143604536736
Please
note that not all of the Transit vans are the same in the Most Forward
area and may require more adhesive if there is a gap or some sanding on
the adapter.
The outside adapter will fit anywhere along the cargo part of the roof. Longer screws than came with the vent fan may be needed.
The vent adapter outside dimension is 16 3/4 X 16 3/4. If you are using a Maxxair vent our adapter fits the Maxxair fan deluxe series, other Maxxair vents have a wider flange. You will need a wider adapter. Please text Kim at [phone removed by eBay] for help.
The option with butyl tape includes 64" of tape. If
the butyl tape is stuck to the plastic, put it in the freezer for 30
minutes. It will release, then let the butyl tape return to room
temperature.
The level shown in the photo is not included.
We make adapters to fit air conditioners and adapters for offset locations. Please contact us so we can verify size and location.
Roof Vent Adapter Install Tips
We
recommend Sikaflex 221. Locate and cut the 14 x 14 hole. You can use
the adapter as a guide to mark the hole. Stay clear of roof support
beams.
Make a tape line 1/4" beyond the adapter perimeter.
De-gloss
the area with a Scotch-brite pad. No need to scuff, just dull the
paint. Clean with isopropyl alcohol and let dry thoroughly. Blow dryer
if it's wet and/or cold out.
Apply three 1/8" beads of the
Sikaflex on the face of the adapter. Then, press the adapter down onto
the roof until the adhesive oozes out the sides. It's not necessary to
clamp. If you do, use several lightly set clamps and spread out the
clamp force over the whole surface area.
Using the adhesive
that oozes out, make a fillet around the adapter with a double gloved
finger. Pull the tape within 15 minutes. Cure is fast on outside. Let
cure overnight and then proceed with the fan install.
If you
purchased our Interior Framing Strips, using the hole that you cut
locate where the transverse strips need to be placed on the longitudinal
strips. Assemble the interior frame with the 2" screws provided. Once
the frame is assembled it will be glued to the interior side of the roof
using Sikaflex 221. If the strips ordered are not bay specific, then
you may need to cut them to the length of the panel you are installing
it in.
We recommend using butyl tape for the fan install. Cover
the fan flange with 1" wide tape. Place the flange onto the adapter and
press down. Then drill pilot holes through the adapter and into the van
roof. You may need the 4 longer screws provided for the corners. Tighten
all screws very lightly against the fan flange. Some butyl will ooze
out which you can trim off.
Coat the fan flange, adapter and
onto the roof about 1/2" with self-leveling Dicor or brush-on Flexseal.
Some sealants will melt the fan plastic so you might try it on a portion
of the interior bezel first. You will cut a lot of that piece off.
Good idea to check the integrity and reapply the sealant every so often.
**Please
note, if you purchased butyl tape with this order and the butyl tape is
stuck to the plastic, place it in the freezer for 15 or 20 min. It
will release, then let it return to room temperature.
